| contents | It has been previously shown that multidimensional $f(R)$ gravity
{can lead} to a two-brane structure.
In this paper, we analyze such a model with a spatially flat 4D de
Sitter (dS) cosmology {whose Hubble parameter $H$ determines the
universal energy scale}. We show that the two-brane metric is
nucleated at the highest energies. The distance between the branes
grows gradually as the energy decreases, tending to a finite value at
zero energy density.
It is stated that the physical parameters such as the 4D Planck mass,
the Higgs vacuum expectation value, and vacuum energy density vary
with the evolving universal energy scale, even on the classical level.
We also show that the Higgs vacuum expectation value is different on
different branes. |
